ELEAZER Aniswonrn, OF WILMINGTON, DELAWARE.

IMPROVEMENT IN BELT-CLAMPS.

Specification forming part of Letters Patent No. 143,604, dated October14, 1873; application filed July 26, 1873.

To all whom it may concern:

Be it known that I, ELEAZER AINSWORTI-I, of Wilmington, in the c ountyof New (Jastle and State of Delaware, have invented a new and ImprovedBelt-Clamp, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a top view of myimproved belt-clamp as applied to the belt to tighten the same Fig. 2,an end view of the same and Fig. 3, a

detail vertical section through the clamp to show the manner of gripingthe belt.

Similar letters of reference indicate corresponding parts. The object ofmy invention is to construct an improved belt-clamp for drawing the endsof the belt together, and tighteningthe same,

for lacing and other purposes. My invention .base piece B and the toppiece B which are connected by suitable thumb-screws 0. .Both pieces, Band B are grooved at their inner sides, taking hold of the belt-likejaws, as in dicated in Fig. 3, to prevent its slipping. Piece B isrounded ofi at one side and straight at the other, so that it may beswung openon one screw, 0, and be quickly attached to the belt. The holefor the other thumb-screw, O,

in piece B is slotted for opening and closing the same on the belt. Theends of piece B are provided with recesses a, and at their outer edgesat the off side of the belt ends with lugs 12. Rods D extendlongitudinally in recesses a, and connect clamps B, having right andleft hand screw-threads, with nuts d working thereon. A pin or ratchet,E, is placed centrally on rods D betweenthe clamps B, for turning rodsD. After the clamps B are applied, the rods D connect them, as the lugsI) serve to retain the nuts d in fixed position v on clamps B. Each turnof the ratchet or pin E produces then the gradual approach of clamps Band, consequently, the tightening of the belt A, for lacing, &c.

The whole belt-clamp may be made of wood,

iron, or other suitable material, and accomplishes the purpose in arapid and efficient manner. 7 1

Having thus described my invention, I claim as new and desire to secureby Letters Pat- (int-:-

1. The combination, with clamps B having stop-pins b, of the right andleft hand threaded rods D and nuts d, as shown and described, to operateas specified.

2. The clamp B, consisting of base piece B with end recesses a and lugs12, top piece B having slotted hole for opening and closing, andthumb-screws G for attaching them to belt A, constructed substantiallyas set forth.
